Somewhere there is a picture similar to that one with Oklahoma County Sheriff's Department K9 Ben on my arm. At the time my free hand had a grip on the end of the sleeve, and I was spinning in circles. We were locked eye to eye and I swear he was smiling at me.
Two years or so later Ben had to be put down after contracting a blood disease at the site of the Murrah Building bombing. He was a damn good K9 and really good with kids. It was really funny, he would remember the decoy, and after the training come up and "nip" the heels of your boots. It was like he wanted to come back and remind you "HAHA, I won, now pet me or we start again".

Side note: Ben was one of the few "triple threat" dogs in the area. Explosives/accelerants, narcotics and patrol certified.
